==== Target Representation ==== Target Representation
In <<block277316>>, we saw that the block contains the target, in a notation called "target bits" or just "bits," which in block 277,316 has the value of +0x1903a30c+. This notation expresses the Proof-of-Work target as a coefficient/exponent format, with the first two hexadecimal digits for the exponent and the next six hex digits as the coefficient. In this block, therefore, the exponent is +0x19+ and the coefficient is +0x03a30c+.
